Adaptive variable structure guidance system design of a longitudinal automatic carrier landing system

The design problem of guidance system of a longitudinal automatic carrier landing system is considered. The mathematic model of the landing guidance problem is created based on the analysis of the main architecture of a longitudinal automatic carrier landing system. The landing guidance system is designed via adaptive variable structure sliding mode control theory and the stability of guidance system is analyzed. The chattering problem is solved via using hyperbolic tangent. Simulation results indicate that the guidance system has the merits of response fast and tracking precisely and validate the feasibility and reasonability of this method.
